    Which do you prefer, and why? I'm not sure if I should keep mt stock, or upgrade it for a metal one of a new high quality plastic one. Whats the difference?

    I hear mixed reviews and performance issues but considering they all pretty much cost the same im not sure whats is better.


    Cheers

    If possible always choose metal > plastic.

    Definitely……metal! Hop-ups are one of several internal AEG parts that take the most stress during firing, plastic hop-up are generally just a bad idea. In fact, the only guns that tend use plastic hop-ups are lower end AEGs, like Echo1, JG, CYMA, etc. etc.

    EDIT: UrbanMarine, your right. Higher-end gun like TM generally use high quality materials, but MOST bands that use plastic hop-ups are of extremely low quality.

    I am kinda of interested in this Madbull Airsoft Ultimate Hopup Unit for M4/M16 Series Airsoft AEG


    The guys I am going to start playing with play alot dusk/night games and all use tracers. Only thing is my m4 has a plastic body. And I kinda don't want to modify my body to install this. And madbull always comes out with good quality stuff. Anyone have experience with this?

    IDK what to think? I have been told that plastic is better because it can expand and contract much better than metal. But in a hop up i dont want air to escape so i could only assume that metal is better? I have this same question my self.

    as a general guideline I always replace stock plastic hops....I've found that high quality plastic ones generally perform better than metal ones.

    plastic is also easier to work with as it can flex (to a certain degree) to accomodate different guns. I always use plastic hop ups when I'm replacing one for a friend I find they seal easier and hold seal longer. Now my gun has a metal unit but that's because I have the time to reseal every game.

    Plastic FTW

    absorbs vibration better, more resistant to screw damage and cracks like my RS unit.
